Optimizing refolding condition for recombinant tissue plasminogen activator

Low molecular size additives such as L-arginine and the redox compounds have been used both in the culturemedium and in vitro refolding to increase recombinant proteins production. Additives increase proteinrefolding and yield of active proteins by suppressing aggregate formation or enhancing refolding process.In this work, a comparative study was performed on refolding of rec...

The Outcome of Treatment With Recombinant Tissue Plasminogen Activator in Acute Ischemic Stroke

Background: Thrombolytic therapy is the recommended treatment of acute ischemic stroke. It is crucial to evaluate the treatment results with recombinant Tissue Plasminogen Activator (r-TPA) in patients with acute stroke. Objectives: This study aimed to evaluate treatment outcomes with r-TPA in patients with acute stroke in a referral stroke center in Iran. Materials & Methods: In this retrosp...

Destruction of Recombinant Tissue Plasminogen Activator (rtPA) -Loaded Echogenic Liposomes under Dual Frequency Sonication

Background:Echogenic liposomes (ELIPs) encapsulate drugs and gas bubbles within lipid vesicles. The destruction of ELIPs in response to MHz and kHz ultrasound waves has been studied previously. Applying ultrasound above a certain threshold causes encapsulated gas bubbles destruct rapidly by fragmentation or more slowly by acoustically driven diffusion. This study compares the d...

Recombinant tissue plasminogen activator in the treatment of suprachoroidal hemorrhage

BACKGROUND Suprachoroidal hemorrhages are a vision-threatening complication, and poor visual outcome is correlated with increasing hemorrhage complexity. The recommended time of surgical drainage is 10-14 days after the hemorrhage begins to liquefy. We describe a case in which recombinant tissue plasminogen activator (r-tPA), alteplase, is injected within the suprachoroidal space before surgery...
